 |  Here we use a math block that contains nothing but definitions in 
 |  standard TeX format.  It is enclosed in a DIV that doesn't display, so 
 |  that there are no extra spaces generated by having the extra 
 |  mathematics in the text.
 |  
 |  The first macro makes it easy to display vectors using \<x,y,z>
 |  the second uses \newcommand to create a macro
 |
 |-->
<div style="display:none">
\(
  \def\<#1>{\left<#1\right>}
  \newcommand{\CC}{\mathbf{C}}
\)
</div>

<p>
This page uses two different methods to define macros: either putting them 
in JavaScript notation in the MathJax configuration, or in TeX notation in 
the body of the document.
</p>

<p>Some math that used the definitions:
\[
  f\colon\RR\to\RR^3 \hbox{ by } f(t)=\< t+1,{1\over 1+t^2}, \sqrt{t^2+1} >
\]
and
\[
  \{\,z\in\CC \mid z^2 = \bold{\alpha}\,\}
\]
